John Cockburn and antecedents

Re: John Cockburn and antecedents

I have relatives named Coburn. I believe that they may have moved to Maybole from Northern Ireland. Ballymena Antrim.Mary Coburn married Richard McKie 19th August 1884 at Maybole. Elizabeth Jane McKie was born 13 April 1896. Elizabeth was my Grandmother, she married William Robb.Does any of this ring a bell?
